汽车采用钳盘式制动,可提高制动器耐热与防水性能,从而确保车辆制动的恒定性,故当代汽车的前制动很多都配置钳盘式制动器,有些后轮制动也配置钳盘式制动器。钳盘式制动器中,大部分都采用带常导通式传感器的制动摩擦片极限报警装置,2个指示接触点相互串联,当某一边的制动摩擦片磨损达到极限值时,磨断指示接触点装置而使传感器断路,这时指示灯或报警蜂鸣警告驾驶人车辆已到维修期限。
The use of caliper disc brakes, can improve the brake heat and water resistance, so as to ensure the stability of the vehicle brake, so many of the current car front brake are equipped with caliper disc brakes, and some rear wheel brake is also equipped with caliper Brakes. Most of the caliper disc brakes use a brake friction limit alarm with a normally-on sensor and two indicating contacts are connected in series with each other. When the brake disc wear on one side reaches a limit value, the glitch indication Contact point device and the sensor circuit, then the light or alarm beep warned the driver vehicle has reached the maintenance period.
